Math Posts: 281   Location: Henry Clay | The following was on the calculus listserv The program is a pretty nice alternative to Geometer's Sketchpad or WinGeom and is freeware as far as I can tell. In the 5 minutes I played with it, I created some nice things. Anyway here it is for the taking.... Bryson ******************************************************************************************** So this is to let you know about GeoGebra, a marvelous Java-based dynamic-geometry freeware program which unites geometry, algebra and calculus, created by Markus Hohenwarter at the University of Salzburg. GeoGebra was specifically created for use by secondary school students. Triangles and circles are easily created, geometric properties can be explored and points dragged dynamically. Equations of lines and curves are automatically produced as geometric elements are added to a screen, and on the other hand equations can be entered and their graphs are straightaway produced on screen. Points of intersection are located too. And presentation quality diagrams can be created in GeoGebra then printed out or embedded in other documents. The homepage is http://www.geogebra.at/ for further information and downloads. Peter Enge Canberra Institute of Technology | ||
